MACHINE FOR MOLDING CONCRETE BODIES.

srnorrroarron forming part of Letters Patent No. 694,123, aategr w ga V Application filed June 28,1901.

To all whom, it may concern:

Be it known that I, MARION A. VVINGET, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Machines for Molding Concrete Bodies, of which the following is a specification.

My invention relates to the improvement of machines forforming concrete blocks,and has particular relation to machines for forming blocks of this character for building purposes, although the same may be adapted for the formation of street-paving blocks or other similar composition or clay bodies.

The objects of my invention are to provide a simple, reliable, and effective machine for the formation of said blocks having an improved construction and arrangement of parts, the details of which will be more fully set forth hereinafter. These objects I accomplish in the manner illustrated in theaccompanying drawings, in which' Figure 1 is a side elevation of my improved machine, showing the movable parts in their lowered positions. Fig. 2 is an end view of the same. Fig. 3 is a plan view with the flaring hopper-top removed. Fig. i is a view in perspective of a portion of the moldboard. Fig. 5 is a detail view in elevation of a tool which I employ in removing the moldboard. Fig. 6 is a view in elevation of a portion of the moldboard, showing said tool engaged therewith. Fig. 7 is a side elevation of the machine, showing the hopper in its elevated position and with its sides and ends thrown open. Fig. 8 is a sectional view on linemacof Fig. 7. Fig. 9 is a sectional view on line y y of Fig. 1. Fig. 10 is a detail view in perspective, illustrating the hinge connection of one of the hoppersupporting yoke-arms with the hopper-body. Fig. 11 is a sectional view through one of the hopper ends, and Fig. 12 is a detail view in perspective of a modified form of moldboard.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ a suitable framework comprising vertical standards or uprights 1 and cross-pieces 2,which connect said standards. Between two of the lower cross-pieces is journaled a horizontal shaft 3, and on the ends of said shaft are carried Serial No. 66,333. on; ma.

crank-handles 4. Mounted onthe shaft 3, on

the inner side of one of the frame-standards,

is a pinion 5, the latter gearing with a gearwheel 6, carried on one end of a shaft 7, which runs parallel with the shaft 3, said shaft 7 carrying on opposite sides of the center of its length pinion-wheels 8. The teeth of these pinion-wheels mesh with the teeth of vertical rack-bars 9, the latter adapted to extend upward, as shown, through openings formed in a stationary horizontal floor or hopper baseplate 10. WVith opposite sides of each of the rack-bars 8 are connected the inturned arms of upwardly-extending yokes 11. The arms of these yokes may pass loosely through suitable guides 12', which project from the framestandards 1, and the upper ends of said yokearms are, as indicated more clearly at 13 in Fig. 10 of the drawings, hinged or pivoted to the ends of the sides 14 of a hopper 15, the latter being adapted to extend upwardly between the top-frame bars 2. Of this hopper 16 represent the end pieces, the lower portions of which are hinged, as indicated at 17, to a hopper-bottom plate 18, which is adapted to bear upon the upper side of the stationary base-plate 10. The hopper thus formed is adapted to have suitably although detachably supported thereon a flaring top extension or mouthpiece 19. Between the inner sides and ends of the stationary top frame of the machine and the sides and ends of the hopper I journal in said top frame horizontal rollers 20. (See Figs. 3 and 9.) Fixed in connection with the rigid base-plate 10 are the bases of thedesired number of upwardly-projecting cores 21, these cores extending, as shown, through the plate 18 and through core openings formed in the moldboard 22. In Fig. 7 of the drawings I have shown an additional core 23, mounted vertically on the inner side of each of the hopper ends -16; but it is obvious that these cores may project upward from the fixed base 10, as prescribed, for the cores 21.

In constructing the moldboard 22 I provide on the under side of each end thereof suitable eyepieces or loop projections 24, which may extend within recessesor pockets 25,formedin I the upper side and end portions of the plate 18, thus permitting the under surface of the moldboard to contact with the upper surface of said plate.

When the hopper and rack-bars are in their lowered position, it will be seen that the sides and ends of the hopper will stand in vertical positions and that they will be held against outward movement by contact with the rollers 20. Assuming that said hopper is thus supported in its lower position, the material from which the building or other block is to be produced is introduced into the hopper through its mouth and said hopper filled to the desired depth about the cores. By then rotating the shafts 7 through the turning of the crank-handles 4 the rack-bars 9, together with the hopper, are raised, owing to the gear engagement of the pinions 8 with the teeth of said racks. When the hopper has .thus been elevated until the lower portions of the sides and ends thereof are beyond the centers of the rollers 20, it is obvious that the hopper-mouthpiece 19 being removed said sides and ends will drop outward to the positions indicated in Fig. 7 of the drawings and that the block previously formed within the hopper will thus be exposed in position for removal. In removing said blockl preferably employ a tool such as is indicated in Fig. 5 ofthe drawings, which consists of a central handle portion 26, having terminal forks 26, the ends of which are'turned outward and adapted to be detachably engaged with the eyes 24 in the ends of the moldboard.

It will be observed in connection with the above-described operation that the cores are stationary and that the material forming the block is lifted upward from about said cores, thereby forming the core openings in the block in a manner which is the reverse of that ordinarily employed.

In Fig. 12 of the drawings I have shown a modification in the construction of the moldboard, which consists in providing the same with an angular plate 2'7 of suitable form, the base of which is adapted to be secured to the moldboard, which in this instance is indicated at 28. It will be understood that any desired form of plate may be detachably o'r adjustably secured upon said board 28 for the purpose of severing the block or limiting the same in size by permitting said plate 27 to form when the hopper is lowered a partition for the latter. It will also be understood that the plate 27 may extend upon the moldboard diagonally or otherwise for the purpose of changing the outline of the block, thereby permitting building-blocks of different shapes to be formed. The moldboard 28,

although shown without core-openings, may be provided with the same, if desired, and

used in conjunction with the cores, said plate 27 being arranged between the latter.

From the construction herein shown and described it will be seen that a simple, reliable, and effective mechanism is provided which is particularly adapted for the formation of concrete or other composition blocks for buildof other clay or composition blocks or bodies.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is V 1. In a machine for molding concrete bodies, the combination with a framework and fixed cores projecting therefrom, of a hopper or mold-box adapted to be raised and lowered about said cores, substantially as specified.

2. In a machine for m olding concrete bodies, the combination with a framework and fixed cores supported therein, of a hopper or moldbox having its sides and ends hinged at their lower portions and means for retaining said sides and ends in vertical positions until the lower portion of the hopper is elevated to the top of the frame and means for raising and lowering said hopper, substantially as specified.

3. In a machine for molding concrete bodies, the combination with a framework, a shaft journaled in said framework and pinions on said shaft, of a hopper having hinged sides and ends and rigid cores adapted to extend within said hopper, of sliding rack-bars, supporting devices on said rack-bars connected with said hopper, the teeth of said pinions adapted to gear with the pinions of said rackbar, substantially as specified.

4. In a machine for molding composition blocks, the combination with a framework comprising connected standards and a fixed bed-plate l0 and fixed cores extending vertically from said bed-plate, of a hopper movably supported above said bedplate, a bottom plate 18 in said hopper, a mold-plate 22 removably supported on said bottom plate, the sides and ends of said hopper being hinged in theirv lower portions, rollers journaled between the main frame and the hopper sides and ends and means for raising and lowering said hopper, substantially as specified.

5. In a machine for molding composition bodies, the combination with a stationary framework, a fixed bed-plate 10 therein, rigid cores 21 rising from said bed-plate, a hopper above the bed-plate, a bottom plate in the hopper, vertically-movable rackbars, hoppersupporting arms extending from said rackbars and having a hinge connection with the sides of said hopper, the ends of said hopper having a hinge connection with the bottom plate thereof, rollers journaled in the upper portion of the framework and adapted to retain the sides and ends of the hopper in vertical positions until said hopper has been elevated to a predetermined height and means for raising and lowering said rack-bars, substantially as specified.
